Strengthened with Billet Components for Long-Term Durability

What makes this package a true standout is its billet input, output, and intermediate shafts, which are built to handle the kind of torque that shreds stock parts. These key upgrades make it ideal for trucks running larger turbos, bigger tires, or pushing high boost levels. Best of all, it’s a direct bolt-in replacement, so you don’t have to worry about extra modifications or complicated installation. Whether you’re using your truck for work, play, or both, this Stage 5 package delivers the reliability and performance you need. Keep in mind, a $500 shipping surcharge applies at checkout, but the durability and peace of mind you get with this upgrade make it well worth the investment.
